Patented May 26, 193l UNITED STATES PATENT OFFICE COMPANY, LIMITED, OFTORONTO, CANADA, A. CORPORATION'OF ONTARIO CARBON CONTROLLER FORTYPEWRITING MACHINES Application filed November 15, 1926; Serial No.148,361. Renewed October 22, 1930.

This invention relates to writing machines, such as typewriting machinesand, with respect to its more specific features, to control an actuationof the transfer sheets in conjunction with typewriter printing mechanismof the kind which is ada ted to travel, or shift over the record strips,t e record strips being in superposed relation for manifolding.

One of the objects of the invention is the provision of writing machineadapted for manifold-typing long relatively superposed, paper recordstrips; a machine which lends itself, in a practical and eflicientmanner, to

all the operations and manipulations required to operate on such longsuperposed record strips and produce a number of similar typed copies,and in which the operations of altering the typed matter on any one orall the copies are facilitated and may be speedily and efiicientlyaccomplished.

An objectspecially lending itself to the foregoing object is theprovision'of a'simple and practical device wherewith the actuation andpositioning of the transfer sheets especially a large number ofrelatively superposed transfer sheetsis rendered easy and convenient, sothat underlying record strips may be exposed for inspection andcorrection while the transfer sheets remain in their sequence ofsuperposition relative to the record strips. j

Another object is the provision of a writing machine of the characterreferred-in which all of the superposed transfer sheets for transferringinscription from one record strip to another are caused to lie inrelatively taut condition between and crosswise of the assured, largelywithout the attentionof the operator. u

Other objects of the invention will in, part be obvious and will in partappear hereinafter.

The invention accordingly comprises the features of construction,combinations of ele- EDWARD KIRBY BOTTLE, 0F ELMIRA, NEW YORK, ASSIGNORTO AMERICAN SALES BOOK ments, and arrangements of parts, which will beexemplified in the construction hereinafter set forth and the scope ofthe application of which willbe indicated in the claims.

For a fuller understanding of the nature and obj ects of the inventionreference should be had to the following detailed description taken inconnection with the accompanying drawings, in which: Fig. 1 is aside'elevation of a writing machine embodying the invention, certainparts being omitted for clearness of illustration.

' inclusive.

tween the parallel sidebars 2 of the frame of the machine, the frameincluding legs 3 suitable in number for supporting the platen at aconvenient height for the operator.

, Opposite the advance end of the platen is a clamping jaw 4 which, by asuitable pedal 51, and operative connections therefrom to said clampingjaw, such as the link 52, and levers 53 and 54, and spring 55, may becaused to cooperate with the platen to grip and release the recordstrips at such point. The record strips, in superposed relation, advanceto position over the platen where they may be operated upon by theprinting mechanism of the machine. A large number of record strips insuperposed relation may be employed. For the purpose of illustration,three record strips, 5, 6, and 7 are shown. In Fig. 3 these strips areshown broken away. These strips may come from any suitable source ofsupply, and each strip has a longitudinal series of printed forms andweakened lines between successive forms, the forms on one strip beingadapted to register in superposed relation with those on the other, sothat printing upon the uppermost strip will be transferred to the lowerstrip in the same relation in the printed forms. A part length of one ofthe printed strips on a reduced scale is shown in Fig. 8, the weakenedlines being indicated at 56. To feed the record strips, the clamp 4 maybe lifted by operation of the pedal, the superposed strips grasped bythe operator and drawn across the platen so as to bring the nextsucceeding set of printed forms into inscribing position on the platen.Thereupon the clamp 4 will be permitted to resume its grip on thestrips. This clamp will hold the stripstightly so that the previouslyinscribed sections of the strip may be torn off along the straight edgeprovided by the clamp or along the weakened lines, which latter are inregistry when the forms are.

The numerals 8 and 9 indicate two trans fer sheets, the sheet 8 lyingbetween the two uppermost record strips, and the sheet 9 lying betweenthe two lower record strips. These transfer sheets are adapted totransfer printing impression from the topmost record strip to thosebelow, and may be of usual transfer material as, for instance, thewell-known carbon transfer sheets of paper. The nu.- merals 10 indicatea pair of parallel guide,

guide-rods or bars,rotatably supported along-- side the path of therecord strips. These guide-bars are similar to each other and aresimilarly supported on the frame of the machine, so that description ofone will suflice for both. The numerals 12 and 13 indicate bracketsbolted to the outside of the frame members 2 and providing bearings inwhich the guide-bars 10 are journaled. The bracket 12 has apivoted jaw14 which is adapted to cooperate with an annular groove in the rod 10 tohold said rod from longitudinal movement. A spring 15 is utilized toretain jaw 14 in cooperative relation to the rod 10. The bracket 13carries a split block 16, each section of which is suitably shaped toprovide a bearing surface 17 for the cylindrical end 18 of the guide-rod10. A thumb screw 19 serves to regulate the grip of the bearing surfaceson the guide-rod, so that the resistance to rotation of the guide-rodmay be regulated, or the.guide-'rod held from rotation, as desired. Theguide-rod has a knurled head to facilitate its convenient rotation. Theguide-bars 10 are thus removably connected to the frame of the machine.It will be understood that the above description applies equally toFigs. 1 to 5, inclusive.

Longitudinally slidable on the guide-rods 10, so as to be reciprocallyshiftable lengthwise relative to the record strips, are the transfersheet holders 20 which, in the embodiment of Figs. 3, 4, and 5, includea pair of cylindrical cores made of wood, one core for each rod, thelength of each core being equal to the width of a transfer sheet. Thecores are indicated in dotted lines in Fig. 3. Each of the transfersheets is coiled around and held on the two cores and is adapted tounwind from one core and extend therefrom into transfer relation to therecord strips, crosswise of the direction of advance of such strips, asclearly illustrated in Fig. 5. In the embodiment illustrated in Figs. 3,4, or 5, rotation of either of one of the guide-rods is intended toeffect rotation of the core 20 thereon and consequent feed movement ofthe transfer strips from the other core, for the purpose of bringingfresh transfer surface to the printing point. The rods 10 may be rotatedin either direction. The axial-bearing opening 57 through the cores ismade angular in shape, and the cross section of the bars 10 is similarlyangular, so that rotation of either of said bars will effect rotation ofits core 20, the cores nevertheless being adapted to be reciprocallyshifted longitudinally of the guide-bars, when desired.

- For the purpose of shifting the cores 20, a manually operable,reciprocal, shift-frame may be provided, and may include two shiftableyokes of similar construction, each core being preferably detachablefromf'its yoke. Each yoke is adapted to act as a core-shifter andcomprises a neck 21 and two arms 22 and 23, between which arms the core20 is interposed. The arm 23 of the shiftable yoke comprises two bearingjaws 24 and 25 (Fig. 5), the jaw 24 being pivoted at 26 to the jaw 25.The bearing provided by the cooperative jaws 24 and 25 is suflicientlylarge to permit rotation of the angular guide-bar relative to the yokewithin the bearing and supports the yoke as it is shifted or slidlongitudinally in either of opposite directions along said guide-bar.For holding the bearin jaws 24 and 25 in closed position, a latch 2carried by arm 23 is adapted to engage a tooth 28- 22 and 23 to bevaried so as to adjust the width of the yoke. As illustrated, one end 31of rod 21 is of angular cross-section so .as to enter and fit acounter-part angular aperture 32, in the arm 23. Threads on the end 31receive the nuts 33 for holding the rod 21 in adjusted position on arm23.

Washers 34 and 35 are interposed between the ends of cores 20 and theyoke arms 22 and 23. These washers are shiftable on 'the guide-rods 10,which pass through angular bearings opening therein, and the washersalso serve as gauges for the opposite edges of the transfer sheets wherewound on the cores. It willv be seen that, when the yokes are shiftedlongitudinally on the guide-rods, positive shift of the cores therewithis effected, the washers protecting the edges of' the transfer sheetsfrom injury by direct contact with the yoke arms.

In order that the two transfer sheet holders 20 may be shifted in auniform manner, they are connected for shifting together. To effect thisthe shiftable yokes hereinbefore described are joined across the machinebeneaththe platen 1, by a strong and rigid shifter bar 36, which is apart of the shift frame. As illustrated, the bar 36 is integral with thetwo yoke arms 23, and is bent at 37 to underlie the side frame members 2and may have the upturned part 38, better to escape the knees of theoperator. The yoke arms 23 have elongated bearings as at 40 proyided bythe jaws 24 and 25, which closely fit around the corners of the angularguiderods 10, and relative to which the guiderods 10 may rotate. By thisconstruction, simultaneous shift of both yokes is effected by manuallyshifting either, or by shifting the shifter bar 36, with consequentsimultaneous shift of both holders, orcores 20. It will be seen that thepoints of attachment of the transfer sheets to the shift frame, throughthe cores and yokes, are respectively adjacent each of opposite sides ofthe record strips, so as to readily permit the transfer sheets to enterbetween the record strips.

In order to minimize chance of the transfer sheets being shifted intoposition to be gri ped by the clamp 4, the extent of their shi t towardthe advance end of the platen may be limited so that the ultimate extentof shift will not be sufficient to carry the transfer sheets intogripping relation with said clamp. To this end the rods 10 may each beprovided with yoke stops 39 longitudinally adjustable on said rods, andagainst which the bearings 40 of the yoke arms 23 are adapted to abut,to arrest the transfer sheets short of the clamp 4'.

In the form illustrated in Fig. 3, the trans- .fer sheets are wound uponcores 20, of which there is one at each side of the path of the recordstrips. A plurality of the transfer sheets, in superposed relation toeach other, are rolled into a coil at one end, on one of the cores, oneend of the assemblage being held on the core by suitable spring clips.The free ends of the sheets are then drawn across the platen andattached to thecore 20 at the other side, so that, when the latter coreis rotated by\ s rotating its guide rod 10, the transfer sheets will bedrawn from one core and wound up on the other, as will be readilyunderstood. It

will be perceived that the transfer sheets lie between superposed recordstrips, so that the path of one of the sheets from core to core islonger than that of the other. In the embodiment' illustrated, the pathof the topmost transfer sheet is the longer, and this sheet acts as adriver and is tautened from core to core by'the drawing operation. Theunderlyingtransfer sheet, however, has a shorter path,

and the drawing operation results in the production of slack in theunderlying transfer sheet, which slack may result in buckling, or loosecondition thereof between. the record strips, so as to interfere withefficient manifold inscription thereby. Suitable provision is made fortautenin the underlying transfer sheet where it lies lmtween the recordstrips and, preferably, the means for doingsois made shiftable with thetransfer sheets. In the embodiment illustrated, referring to Fig. 11,the underlying transfer sheet 9, and all the other underlying tranfsersheets, if more than two are employed, are pressed by a'weighted roller60, which is adapted freely to gravitate in guideways 61 in theupstanding arms 62 of a U shaped frame, the cross piece of which isindicated at 63, this U shaped .frame being removably fixed to the sideface of the shifter frame 36, between one of the cores 20 and theadjacent record strips. The weighted rollers 60 are independent of eachother and rest freely upon the underlying transfer sheets and freelygravitate downwardly in the guide ways61. These rollers 60 may beintroduced at the top of the guideways 61, or they may be introducedlaterally of the transfer sheets upon removal of the keeper plates 64,which latter are'removably attached to the outside take-up device may beduplicated on the 0pposite side of the machine, if desired. As theunderlying transfer sheets are delivered from the coil, the rollers 60take up the slack so that such sheets lie in fiat and fairly tautcondition between the record strips.

Instead of rotating one of the cores 20 to draw the superposed transfersheets across the platen, provision may be made whereby they may beconveniently drawn by hand from one of the coils. To this end the wingnut 19 may be screwed up tightly to prevent rotation of one of the guiderods 10, as, for

.instance, the guide rod illustrated at the transfer material over theplaten.

upper part of Fig. 2. Thereupon, a rod or bar 65 may be utilizedsimultaneously to grip all the transfer sheets against the surface ofthe core. In this case, however, 1t is preferred to flatten the surfaceof the core as illustrated at 66 in Fig. 10, so that the bar 65 mayeffectively grip the transfer sheets throughout their width. The bar 65may enter slots 67 and 68 in the washer 35 and arm 23, respectively, soas to be removably held in position. A tight fitting of the bar 65 inthe slots will be sufficient to cause the bar to firmly grip thetransfer sheets and hold them in place. By raising the bar 65, grip onthe transfer sheets will be relieved. Thereupon the transfer sheets maybe grasped by the hand and drawn from the coil on the opposite side soas to bring fresh It will be noted, also, that each transfer sheet maybe separately manipulated and tensioned across the platen so as to avoidslack. The bar 65' may have a straight edge 68 adjacent the transfersheets, so as to provide a tearingbar, against which the transfer sheetsmay be readily torn, and the used portions thus removed. It will benoted that the bar 65, like the core 20, is shift-able with the transfersheets and with'the shift frame 36.

The typewriting mechanism is indicatedgenerally by the numeral 70. Thisconsists of a typewriter which is shiftable over the platen 1, both inline spacing and letter spac ing directions. The illustration herein ofthe typewriter is largely diagrammatic, it being sufficient to say thatit is a regularly operating typewriting machine shiftable as stated, andit may be similar to the shiftable printing mechanismcommonly employedin typewriting machines having a large rela tively stationary,flatplaten, such as the platen 1 referred to herein. An example of sucha tvpewriting machine is found in the Elliott- Fisher billing machine,which is commonly used. The shiftable typewriting machine has the usualinking ribbon, which shifts with the typewriting machine both in linespacing and in letter spacing directions, the.

type of such machine striking against the ribbon, which ribbon is thuspressed against the uppermost record strip and gives the inscription onthe top record strip. It will thus be seen that the typewriter ribbonacts as a transfer sheet and that it is independent of the othertransfer sheets, 8 and 9. In Fig. 1 the inking ribbon isdiagrammatically illustrated at 71 and a striking type at 72, it beingunderstood that suitable guides on the typewriting machine support theribbon in position opposite the rinting point, where struck by the type.upporting the printing mechanism, and practically forming a part of theframe thereof, is a carriage which is reciprocally shiftable over therelatively superposed record strips. In its main construction thecarriage is of the form commonly employed in the Elliott-Fisher billingmachine, and includes the front and rear parallel bars 75 and 76 oinedby the arallel longitudinally extending bars 77 an 78, to form a rigidrectangular frame through the opening in which the record strips areexposed, and may be reached by the printing mechanism of the typewriter.On the front bar 75 of the carriage are rollers 79, which rest upon theside frames 2 and support the carriage at the front, the side frames 2acting as tracks. At the rear are the large rollers 80 and 81 j-ournaledon a shaft 82 supported in brackets extending rearwardly of thecarriage. At the outer sides of the rollers 80 and 81 are the pinions 83and 84 fixed to the shaft 82, and engaging racks 85 and 86, fastened tothe adjacent side frames 2. Fixed to rotate with the shaft 82 is thefinely toothed ratchet wheel 87. The numeral 88 indicates a pawl havingseveralz teeth adapted to cooperate to engage the teeth of the ratchetwheel and rotate the latter. The pawl 88 is pivoted to an intermediatepawl arm 89 oscillatably mounted concentrically with the shaft 82. Thearm 89 is stressed to rearward position by a spring 90, so that the pawl88 lies against a stop pin 91. By rotating the pawl arm 89 to the left,Fig. 1, the pawl 88 will cooperate to rotate the ratchet wheel 87 andthereby rotate the pinions 83 and 84, so as to shift the carriage to theleft,relative to the platen, the direction of shift in the embodimentillustrated being for line spacing. For actuating the pawl arm 89 toeffect shifting, it 'is' operatively coupled with an oscillatory rod 92mounted on the side of the carriage and extending to the front, where itis provided with a handle 93 for manually actuating the same. Fixed torod 92 is a cam arm 120 which lifts a gravitatively movable plunger 121to in turn contact with and move a projection 122 of an arm 123journaled on shaft 82. The retracting spring is connected to arm 123, asshown in Fig. 1. Arm 123 has a pin 124 engaging a slot in pawl 88. Byrotating the handle 93 in one direction the carriage is caused .to shiftuntil the arm 123 is arrested by the stop 94:. Upon releasing the handle93, the arms 89 and 123 and pawl 88 are retracted, ready for againrotating the ratchet wheel 87 in line spacing direction. It will beobserved, however, that the carriage frame may be grasped and moved 5.back and forth at will in line spacing direction, when the pawl 88 isout of engagement with the ratchet wheel. The ratchet wheel and itsactuating members, including the handle 93, are for the purpose ofprogressively advancing the carriage in line spacing direction, line byline, as it were. The detailshifting mechanism for the carriage justdescribed is similar to that employed in the Elliott- Fisher billingmachine to which reference has been made. I On the carriage rests thetypewriting machine 70, being supported at the front by the rollers 94resting on the bar 75, and being supported at the rear by the rollers 95restzq ing on the bar 76, the typewriting machine being held againstmovement in line spacing direction relative to the carriage, but beingreciprocally shiftable on the carriage in letter spacing direction, inthe present embodi ment, and as exhibited in the Elliott-Fisher billingmachine aforesaid.

Depending from the bar 7 6, or lateral extensions thereof, are deviceswhich are adapted to be moved into'and out of position to causeshiftmovement of the transfer sheets 8 and 9 in li'ne-spacin direction, withthe carriage. In the em odiment illustrated this means .,consists of adog, or dogs, 100

(Fig. 1) 'pivoted to brackets 101, which brackets are removably attachedat opposite ends of the bar 76. When in lowered position, as illustratedin Fig. 1, the dogs 100 are adapted to contact with the yoke arms 22 ofthe shiftable frame, and thereby shift said frame and the transfersheets carried thereby, in line-spacing direction. In the embodimentillustrated in Figs. 1 to .5, inclusive, shift of the carriage towardthe left, Figs. 1 and 2, causes shift of the shift frame by thedogscoming into contact with the arms 22 and thereafter pressing theshift frame to the left, the carriage being freely shiftable to theright independently of the shift frame. When desired, however, the arms22 may be provided with a retainer arm 102, Fig. 12, pivoted to the arm22 and movable into and out of position opposite the dog 100, so that asthe carriage shifts to the right, Fig. 2, the shift frame will movetherewith.

, To arrange the machine for operation, the

printing mechanism 7 Owill be shifted rear -wardly, and the severalrecord strips drawn from their supply" into position over the platen 1,the lowermost record strip lying on the platen. Thereupon, the otherrecord stripswill be thrown back and the lowermost transfer sheet laidin position on the lowermost record strip. Then the other record stripsare replaced in succession over the pIaced transfer sheet, andinterleaved with the other transfer sheets, as will beunder stood. Thenthe free ends of the transfer sheets are attached to the core at theopposite side'of the machine, beingdrawn as taut and smooth as desired.The advance ends of the record strips are then laid under the clamp jaw4. The machine is then ready for typing the record strips. The printingmechanism may be shifted longitudinally of the platen by shifting thecarriage, and crosswise of the platen by shifting the printing mechanismon'and relative'to the carriage. It will be understood that thecrosswise shifting of the printing mechanism may be accomplished eitherby hand or bythe letter spacing key of the typewriter, as usual inmachines of the type herein referred to, and exemplified in theElliott-Fisher billing ma chine.

Printing on the topmost record strip will be transferred to theunderlying record strips by the interposed transfer sheets. Typinghaving been completed, the pedal 51 may be actuated to relieve the clamp4 from grip on the record strips and. the latter may be grasped by theoperator and drawn longitudinally along the platen so as to bringsucceeding printed forms into positionon the platen, all withoutdisturbin the transfer sheets. However, should it be desired to alterorcorrect the typed inscription at any point, the printing mechanism maybe shifted rearwardly a sufficient amount, and the transfer sheetsmay'also be shifted to position uncovering transferred impression on theunderlying record strips. Then, by freeing the record strips from thefront clamp 4, they may be lifted and thrown back at will, so as toexpose thetransferred impression on any one of them, and correction mayconveniently be made as desired. It will be noted that the may berestored to superposition, and this superposition will be the same asbefore, with v the several transferred inscriptions in superposedregistry with each other. Thereupon, theshlft frame may be actuated toreturn the a transfer sheets to position required formanifoldingimpression, as before. It will. be seen, therefore, that corrections,alterations,

' additions, and the like, may beapplied to the underlying recordstrips, while maintaining superposed interleaved arrangement of thetransfer sheets ateither side of .the platen.

When a transfer sheet is sufiic'iently wide to .transfer sheets, andwithout detaching-the v cover the usual writing spacefit maybe un- '22,before the printing point has reached the edge 105 of said transfersheets, and thereafter said transfer sheets will be shifted with theprinting mechanism as the latter shifts in line spacing direction. Whendesired, the dogs 100 may be readily turned upwardly and held out ofposition for effecting shift of the underlying transfer sheets by thecarria e. Inasmuch as the edges 105 of the trans er sheets shift towardposition underlying clamping jaw 4, it is-intended that the bearings 40shall contact with the stops 39 before this happens. This arrest of theshifting of the transfer sheets will prevent clamping of the transfersheets by the clamp 4 and avoid tearing of such sheets when the shiftframe is moved in the opposite direction. It will be noted that when thetransfer sheets 8 and 9 and the printing mechanism are in relativeposition to manifold printing impression, the ink ribbon transfer sheet71 is in superposed relation to the transfer sheets 8 and 9, whichunderlie record strips, and it will be further noted that,notwithstanding that the ink ribbon transfer sheet is independent of theother i transfer sheets, and at times is shifted independently of thelatter, nevertheless, provision is hereby made for maintainingsuperposed relation between the ink ribbon transfer sheet and the othertransfer sheets during shift of the ink ribbon transfer sheet in linespacing direction.

By the provision of the slack take-u means, the underlying transfersheets, thou uncoiling from one core and coilin on t e other, arenevertheless kept taut an smooth between the record strips. As explainedin connection with the flat-faced core illustrated in Figs. 2 and 10,the underlying transfer sheets may be drawn" from one core by hand sothat all shall lie in smooth, taut condition between the record strips,the bar affording means for tearing 011' used portions of the transfersheet's. Inasmuch as the cores 20 are separate from the washers 34 and35, and

inasmuch as the yokes are adjustable in width through theinstrumentality of the nuts 33, it will be seen that the machine isadapted to accommodate'transfer sheets of several difierent widths.

It will be noted that in each modification the transfer sheets 8 and 9are so connected to the shift frame that it always remains in flatmanifolding condition between its points of attachment to the frame,whether shifted in one direction or the other. The cores 20 serve tobrace the transfer sheets widthwise and take the pressure of shifting.Also the tearing bar 65 coacts with the adjacent core to brace thetransfer sheets widthwise. Thus there need be practically no crumplingof the transfer sheets 8 and 9 during their shift movements.

Since certain changes may be made in the above construction, anddifferent embodiments of the invention could be made without departingfrom the scope thereof, it is intended that all matter contained in theabove description or shown in the accompanying drawings shall beinterpreted as-illustrative and not in a limiting sense.
